Police inquiry under way after death at Tonnau Festival
An 18-year-old woman has died following a medical emergency at the Tonnau Festival in Llanfaethlu, Anglesey. North Wales Police said she died in hospital and that the death is being treated as unexpected while investigations continue. The coroner has been informed.
Festival organisers confirmed the incident occurred in the early hours of Saturday and said the remainder of the event was cancelled to allow emergency services and local authorities to carry out their work. They said welfare and medical teams responded immediately on site and that they are cooperating fully with inquiries.
“Everyone at Tonnau Festival is deeply saddened to confirm that a festival attendee tragically passed away in the early hours of Saturday morning following a severe medical emergency… We made the decision to close the remainder of the festival and have asked people to vacate the site when it is safe for them to do so.”
The organisers added that their thoughts are with the woman’s family and friends and that they would not comment further out of respect for the family’s privacy. Police have not released additional details at this stage.
What is known so far
- An 18-year-old woman became unwell at Tonnau Festival and later died in hospital.
- North Wales Police say the death is being treated as unexpected; the coroner has been notified.
- Festival organisers cancelled the rest of the event and asked attendees to leave the site safely.
- On-site welfare, security and emergency medical teams provided immediate care, according to organisers.
Context and next steps
When a death is described by police as unexpected, officers typically carry out initial enquiries to establish the circumstances. Referral to the coroner is standard practice, allowing for an independent process to determine how someone died. That may involve reviewing medical information, speaking with witnesses and, if required, conducting a post-mortem examination. No conclusion about cause has been shared publicly at this time.
The decision to call off the remainder of the festival means the site can be secured and emergency services can work without interruption. Organisers have indicated they are assisting authorities. Attendees were asked to leave the venue when safe to do so, and the site has been winding down since the announcement.
Local impact
The incident will be felt across the local community in and around Llanfaethlu, where seasonal events draw visitors and volunteers. While large gatherings routinely include welfare and medical provision, serious incidents remain rare. The focus for the coming days will be on supporting those affected and allowing the formal processes to conclude. Authorities have not issued any separate public safety alerts linked to this case.
